I put down bath towels for the first couple weeks. It gives them grip and no chips to eat. When I am done with them, spray them off with garden hose and then launder them for the next time. Works perfect.My TSC won’t order it for me so I had to order it thru Amazon. I put the chicks and keets on a piece of AstroTurf this morning, figured I could hose it off every day. Anybody done that? Having trouble getting hay at a reasonable price. Is there an age I could raise everyone together to safely before separating?
